What Are Bitcoin Private Keys
How Bitcoin Private Keys Are Generated Us

There are random generated Bitcoin private keys, converted into WIF format and hashed to addresses. After getting Bitcoin address we check the quantity of transactions(Tx) and get its balance.If you see any address with transactions, we will store this address into leak database and will try to notify the owner.
Because this address was usedpreviously, it may be active now.Nobody is supposed to get these Bitcoins.

In cryptocurrencies, a private key allows a user to gain access to their wallet. The person who holds the private key fully controls the coins in that wallet. For this reason, you should keep it secret. And if you really want to generate the key yourself, it makes sense to generate it in a secure way.

Feb 12, 2015 A private key is just a number picked at random. The private key is used to generate the public key through an irreversible process. In the case of Bitcoin the Private key is turned into the Public key through Elliptic Curve Cryptography or ECC for short. If you lose your private key you can't access your Bitcoins, and if someone else finds it out they can steal them. Bitcoin private keys are very or almost impossible to hack, but with an understanding of how they are generated, we have come to develop this software that will provide you with the private key and password of a specific address you want. Now this works in a way that will stress you a little bit but your success is guaranteed.

Each private key is generated anonymously meaning even the site that generated the private key can not give you the same private key for that address if you regenerate again.
Leaked bitcoin private keys collected by us. We collected leaked bitcoin private keys from different sources. Generated base with parts of whole range, collected from GitHub, forums and sites. Also we generated brain wallet addresses and vanity addresses. All private keys are totally free. But we did not recomendate to take used keys.

Here, I will provide an introduction to private keys and show you how you can generate your own key using various cryptographic functions. I will provide a description of the algorithm and the code in Python.

Do I need to generate a private key?

Most of the time you don’t. For example, if you use a web wallet like Coinbase or Blockchain.info, they create and manage the private key for you. It’s the same for exchanges.

Mobile and desktop wallets usually also generate a private key for you, although they might have the option to create a wallet from your own private key.

So why generate it anyway? Here are the reasons that I have:

You want to make sure that no one knows the key
You just want to learn more about cryptography and random number generation (RNG)

What exactly is a private key?

Formally, a private key for Bitcoin (and many other cryptocurrencies) is a series of 32 bytes. Now, there are many ways to record these bytes. It can be a string of 256 ones and zeros (32 * 8 = 256) or 100 dice rolls. It can be a binary string, Base64 string, a WIF key, mnemonic phrase, or finally, a hex string. For our purposes, we will use a 64 character long hex string.

Why exactly 32 bytes? Great question! You see, to create a public key from a private one, Bitcoin uses the ECDSA, or Elliptic Curve Digital Signature Algorithm. More specifically, it uses one particular curve called secp256k1.

Now, this curve has an order of 256 bits, takes 256 bits as input, and outputs 256-bit integers. And 256 bits is exactly 32 bytes. So, to put it another way, we need 32 bytes of data to feed to this curve algorithm.

There is an additional requirement for the private key. Because we use ECDSA, the key should be positive and should be less than the order of the curve. The order of secp256k1 is FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364141, which is pretty big: almost any 32-byte number will be smaller than it.

Naive method

So, how do we generate a 32-byte integer? The first thing that comes to mind is to just use an RNG library in your language of choice. Python even provides a cute way of generating just enough bits:

Looks good, but actually, it’s not. You see, normal RNG libraries are not intended for cryptography, as they are not very secure. They generate numbers based on a seed, and by default, the seed is the current time. That way, if you know approximately when I generated the bits above, all you need to do is brute-force a few variants.

When you generate a private key, you want to be extremely secure. Remember, if anyone learns the private key, they can easily steal all the coins from the corresponding wallet, and you have no chance of ever getting them back.

So let’s try to do it more securely.

Cryptographically strong RNG

Along with a standard RNG method, programming languages usually provide a RNG specifically designed for cryptographic operations. This method is usually much more secure, because it draws entropy straight from the operating system. The result of such RNG is much harder to reproduce. You can’t do it by knowing the time of generation or having the seed, because there is no seed. Well, at least the user doesn’t enter a seed — rather, it’s created by the program.

In Python, cryptographically strong RNG is implemented in the secrets module. Let’s modify the code above to make the private key generation secure!

That is amazing. I bet you wouldn’t be able to reproduce this, even with access to my PC. But can we go deeper?

What Are Bitcoin Private Keys

Specialized sites

How Bitcoin Private Keys Are Generated Us

There are sites that generate random numbers for you. We will consider just two here. One is random.org, a well-known general purpose random number generator. Another one is bitaddress.org, which is designed specifically for Bitcoin private key generation.

Can random.org help us generate a key? Definitely, as they have service for generating random bytes. But two problems arise here. Random.org claims to be a truly random generator, but can you trust it? Can you be sure that it is indeed random? Can you be sure that the owner doesn’t record all generation results, especially ones that look like private keys? The answer is up to you. Oh, and you can’t run it locally, which is an additional problem. This method is not 100% secure.
